|Route outline (key)|
The B3047 runs alongside the River Itchen through mid-Hampshire.
It starts on a roundabout on the A31 east of Bishop's Sutton, and heads westwards through the village into New Alresford, briefly multiplexing with the B3046 through the town centre. It then crosses the now-disused Alton - Winchester line and TOTSOs to the right - the road ahead being a spur of the B3047 leading back to the A31.
After this, the road changes character to a more rural and winding route, closely following the south bank of the Itchen through Itchen Stoke and Itchen Abbas. The M3 is crossed without a junction and the road then meets the A33 at the north end of the Winchester Bypass.
The A33 is crossed via a staggered crossroads, after which the B3047 takes over part of the historic Roman Road from Basingstoke to Winchester into Winchester city centre. It TOTSOs left onto Hyde Street before ending at the bottom end of the street at traffic lights on the B3330.
About half of the current B3047 consists of downgraded A roads. The original route of the B3047 was from west of Alresford to King's Worthy. The section east of here through New Alresford was the original line of the A31 before the Alresford Bypass opened around 1988, which explains the TOTSO in the area.
The section west of the A33 was the original line of the A33 itself, which then became the A3090 when the Winchester Bypass opened. It was renumbered to an extension of the B3047 when the M3 was completed through Twyford Down and all A roads in Winchester were downgraded.
